Facilitation of frequency selective scheduling for 5g or other next generation network

Abstract

Sub bands can be scheduled with optimal modulation and coding scheme (MCS) when the user equipment reports the sub band channel quality indicator (CQI) and sub band pre-coding matrix index (PMI). The network can use multiple downlink control channels to indicate the sub band resources and the corresponding MCS for that resource allocation. By using multiple downlink control channels to indicate the sub band MCS, the network can use resources more efficiently.
